摘要： BACKGROUND: Dinotefuran (DNF) is a neonicotinoid insecticide with strong systemic, poisoning and gastric toxicity, which is no cross-resistance with the existing pesticides, but its toxicity to environmental organisms such as bees and earthworms is high. The development of environmentally responsive pesticide controlled-release agents using nanomaterials to process the agents by physical or chemical methods can improve the utilization of the pesticide and better utilize the active molecules of the pesticide. RESULTS: To enhance the performance of dinotefuran, UiO-67 was prepared, characterized, and then combined with dinotefuran to form dinotefuran-UiO-67 (DNF@UiO-67) nanocomposites. Compared with dinotefuran, DNF@UiO-67 nanocomposites significantly increased the wettability and photolysis resistance of dinotefuran. Dinotefuran was loaded on UiO-67 without influencing its original activity and was more efficient in the long-term control of pea aphid compared to dinotefuran. The treatment of pea seeds with different concentrations of DNF@UiO-67 did not significantly affect the germination and growth of pea seeds and ensured the normal growth of plants. DNF@UiO-67 reduced the acute toxicity to earthworms and bees. These improvements imply that the DNF@UiO-67 nanocomposites could be used as a potential formulation to improve insecticidal activity and enhance its safety for environmental organisms of dinotefuran. CONCLUSION: This study not only develops DNF@UiO-67 nanocomposites to improve the performance of dinotefuran while maintaining its original insecticidal, but also provides a new idea for the application of dinotefuran in agriculture. Our findings will provide more possibilities for the application of DNF@UiO-67 nanocomposites as an effective and environmentally friendly formulation in agriculture.
